Hi everyone,
i was about to write a new message to this list to explain my new
experiencies with "the ls problem".
This morning i updated both fuse and glusterfs to the latest tla
versions, i used to have mainline2.5-patch 690, now i've got patch 736.
The thing is that i used to have "ls slow" commands when there was
"some" activity in the filesystem.
But with today's update, the system is even slowler, with an empty
filesystem, with no activity at all.... ls is really really slow.
is that normal?
these are extracts from my log files:

Nothing a part from the glusterfs version has changed... i mean... conf
files are the same.... same machines.... and so on.....
En/na Reinis Rozitis ha escrit:
ls commands on modern GNU/Linux systems run xattr calls on each entry for
ACL purposes. This can turn out to be pretty expensive in terms of
performance.
Thanks,
thats what I thought of. Maybe worth to add to the FAQ or some other docs so
it doesnt turn out as WTF - factor.
